AWS Databases for Real-Time Applications
Extreme performance at cloud scale
Real-time applications such as caching, session stores, gaming leaderboards, ride-hailing, ad-targeting, and real-time analytics need microsecond latency and high throughput to support millions of requests per second. Developers traditionally relied on specialized hardware, proprietary in-memory data stores, and workarounds such as disk-based databases combined with data reduction techniques to manage data for real-time applications. AWS offers high performance in-memory services that are purpose-built to power your real-time applications:
For applications that need microsecond latency and support for millions of requests per second, you can use Amazon ElastiCache, a fully managed, in-memory caching service. Amazon MemoryDB for Redis is a Redis-compatible, durable, in-memory database service that delivers microsecond read latency and single-digit millisecond write latency. When you need millisecond latency with Amazon DynamoDB, you can add on DynamoDB Accelerator (DAX), an in-memory cache.
ElastiCache can scale-out, scale-in, and scale-up to meet fluctuating application demands. With MemoryDB, scale seamlessly from just a few gigabytes to over one hundred terabytes of storage per cluster to meet the needs of your applications. With DynamoDB, you can build applications with virtually unlimited throughput and storage.
Fully managed or serverless
You don’t need to worry about database management tasks such as server provisioning, patching, setup, configuration, backups, or recovery. AWS continuously monitors your clusters to keep your workloads up and running so that you can focus on higher value application development.
Secure and compliant
AWS databases are built for business-critical, enterprise workloads, offering high availability and reliability. You have oversight of security with Amazon VPC and encryption in-transit and at rest. Compliance with PCI, HIPAA, and FedRAMP ensures that you can meet strict regulatory requirements.

Amazon MemoryDB for Redis is a Redis-compatible, durable, in-memory database that delivers ultra-fast performance and Multi-AZ durability. Because MemoryDB is compatible with open source Redis, Stack Overflow’s “Most Loved Database” for five consecutive years, you can use flexible Redis data structures to build applications quickly. MemoryDB stores your entire database in-memory and uses a durable, Multi-AZ transactional log, so you can use it as an ultra-fast, primary database. Build modern, microservices applications with MemoryDB to achieve microsecond read and single-digit millisecond write latency and high throughput.
Used for: user content data stores, session management, geospatial indexing , chat and message queues, real-time streaming, fraud detection, streaming IOT device data, and more.
Amazon ElastiCache offers fully managed Redis and Memcached. Seamlessly deploy, run, and scale popular open-source compatible in-memory data stores. Build data-intensive apps or improve the performance of your existing apps by retrieving data from high throughput and low latency in-memory data stores.
Used for: Caching, session stores, gaming & sports leaderboards, real-time analytics, streaming, geospatial, pub/sub apps, and more.
Amazon DynamoDB, a key-value database that gives you single-digit millisecond performance at any scale. DynamoDB Accelerator (DAX) delivers up to a 10x performance improvement – from milliseconds to microseconds.
Used for large traffic web applications that automatically scale up and down during spikes, or personalized mobile apps, and low latency games for mobile, console, and desktop.
Amazon ElastiCache for Redis is a great choice for implementing a highly available, distributed, and secure in-memory cache to decrease access latency, increase throughput, and ease the load off your relational or NoSQL databases and applications. ElastiCache can serve frequently requested items at sub-millisecond response times, and enables you to easily scale for higher loads without growing the costlier backend databases. Database query results caching, persistent session caching, and full-page caching are all popular examples of caching with ElastiCache for Redis. Learn how to build a caching application with ElastiCache for Redis.
Amazon ElastiCache for Redis is highly suited as a session store to manage session information such as user authentication tokens, session state, and more. Simply use ElastiCache for Redis as a fast key-value store with appropriate TTL on session keys to manage your session information. Session management is commonly required for online applications, including games, e-commerce websites, and social media platforms. Learn how to use ElastiCache for Redis as a session store.
Real-time gaming leaderboards are easy to create with Amazon ElastiCache for Redis. Just use the Redis Sorted Set data structure, which provides uniqueness of elements while maintaining the list sorted by their scores. Creating a real-time ranked list is as simple as updating a user's score each time it changes. You can also use Sorted Sets to handle time series data by using timestamps as the score.
